Resumen/Abstract
In this work, an In-fiber Mach-Zehnder Interferometer has been manufactured within a standard optical fiber using direct inscription with a femtosecond laser. Different geometries have been tested in order to enhance the sensitivity of manufactured devices to high temperature sensing, reducing the total device up to 300µm. The achieved results exhibit a remarkably good response for temperature sensing up to 650°C.
